Samsung's are top rated by cnet.com and consumer reports... :shrug:
Samsung is at the top rung of Plasma TV's. I would say only Pioneer's are better.
I have had a Sumsung 5084 for about a year now & it is AWESOME.
Zero problems. The only thing you have to do is make sure you have the latest firmware when you first start it up. Most likely you will (85%), if not it is easy to get it updated.
Unless you plan to game heavily on your TV, more than 2.5 hrs at a time, I prefer plasma over LCD actually. This really is a matter of choice, but I think watching sports is a better experience on plasma.
I would highly recommend this TV. A++
PS. Unless you are a AV freak you dont need to get your set calibrated. Tons of settings can be grabbed off of AV sites or even WIKI to use as a baseline & then just make small tweaks as all TVs will be slightly different, as will personal preference.
Also w/ plasma you will have a "BREAK IN" period.(first 200 hrs of use) This is very important, you can not use 'torch' settings. You want the Plasmas TV to burn evenly in the critical first uses. Make sure you research it online..again easy to find & read up on. Google "Zippy's break in settings" if you get a Samsung.
If you go LCD you dont have to worry about this which is a + for LCD.
Good Luck w/ your choice if you have any questions specifically on Samsungs feel free to ask...
